摘　　要：为了拓展气象服务领域,解决当地主要经济作物向日葵生产中有关农业气象方面的问题。通过试验研究和资料分析,利用河套灌区18年向日葵观测资料和相应气象资料,利用数理统计方法和地理信息系统,计算了向日葵各发育期气温、日照等要素,分析了各发育期适宜农业气象条件,并利用气候资料与气象产量建立了回归模型,通过地理信息系统将河套灌区向日葵种植进行了适宜分区,将河套灌区划分为最适宜、适宜、次适宜、基本适宜等4个向日葵种植区域。In order to expand the weather service effectively,resolve the problems concerning the agro-meteorology of the local sunflower production,Make use of the river set infuses two observation post of area for 18 years,based on statistic method and geographic information system,the sunflower prognosticates data and corresponds the weather data,computing each growth of wheat period air temperature,sunshine etc.main factor,analyze each growth period feat with disadvantageous condition,and made use of the weather data and the weather yield to build up back to return model, infuse the river set through the geography information system the area wheat planted to carry on a feat cent area. The Hetao irrigation area can be divided into 4 suitable districts for sunflower planting. They are the most suitable, more suitable, suitable and basic suitable districts.
